That thermal curve means a panel builder can size this breaker for a 250 A bus and still have headroom in a 50 °C enclosure interior without stepping up to the next frame. Its interrupting ratings climb steeply at lower voltages: 121 kA at 240 V, 75.6 kA at both 415 V and 440 V, 52.5 kA at 500 V, and 4.5 kA at 690 V. The ETU350 electronic trip unit handles adjustable N-conductor protection (OFF, 50%, 100% of phase current) — useful for 4-wire distribution where the neutral needs its own overload curve, not just a solid bar. The 140 mm width across four poles is standard for a 250 A frame in the SENTRON 3VA2 family — it occupies the same footprint as other 4-pole 250 A units in the series, so a panel originally laid out for a sibling MCCB should accept this breaker without re-drilling the mounting plate or reworking the bus bars. IP40 protection on the front (finger-safe against tools and wires over 1 mm) is typical for panel-mounted MCCBs; the enclosure itself provides the overall IP rating. Maximum power loss is 48 W — a non-trivial figure for sealed cabinets; factor that into the thermal budget if the panel runs multiple breakers in a confined space.","metaTitle":"Siemens 3VA2225-4HY84-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2225-4HY84-0AA0 SENTRON MCCB, 250 A continuous, 4-pole, ETU350 release. 121 kA at 240 V.
